I don't > know what 'k' and 'r' are intended to do, so perhaps those too. Coreutils and bash already accept 'h' and 'l' (although they currently effectively ignore size; on a 64-bit platform, 'printf %hhd $((1<<63)' outputs -9223372036854775808; if you want to limit an integral value to one byte, you must mask it yourself). Bash already accepts 'j', 't', and 'z' (it ignores the effective type, and treats them the same as 'd'); while Coreutils rejects those. Bash already accepts 'n'; it must pair to a valid variable name, and assigns into that variable, as in: $ foo=bar $ printf a%n foo $ echo $foo bar Use of 'p' is not accepted by bash or coreutils at present. C2x defines a namespace starting 'w'; deviating from that definition will likely be confusing.
